Anemia
Anemia
A blood type is a classification of blood based on the presence or absence of inherited antigenic substances on the surface of red blood cells (RBCs). These antigens may be proteins, carbohydrates, glycoproteins, or glycolipids, depending on the blood group system. Some of these antigens are also present on the surface of other types of cells. Some of these red blood cell surface antigens can stem from one allele and collectively form a blood group system. It is called The ABO system and it consists of A, B, AB, and O blood types. It is performed based on the reaction of the antibodies of the individual plasma against the antigens that the red blood cells lack. It is important clinically to determine the individual's blood group type …show more content…
There are several blood disorders of different severity. This paper gives a review on the prevalence and major causes of anemia seen on our World.
Anemia is a condition that develops when there is reduction in circulating red blood cell mass which is determine by hemoglobin, hematocrit and RBC count. Hemoglobin is a main part of red blood cells and binds oxygen, for this reason the patient may develop hypoxia due to …show more content…
Causes of blood loss include trauma and gastrointestinal bleeding, among others. Decrease production include iron deficiency, a lack of vitamin B12, thalassemia and a number of neoplasms of the bone marrow among others. Causes of increased breakdown include a number of genetic conditions such as sickle cell anemia, infections like malaria and some autoimmune diseases. Anemia can be undetected in many people, and symptoms can be minor or vague. The signs and symptoms can be related to the underlying cause or the anemia itself.
In conclusion, anemia has been recognized as a major health problem in developing countries for many years: still, this basic problem has not been solved but continues to exist affecting the health, quality of life, and working capacity in billions of people around the world.
Most cases of anemia are due to iron deficiency, which often work in symphony with folate and/or vitamin B12 deficiency and that is due to decrease level of iron that leads to decrease heme in order to decrease hemoglobin, and this happens because of lack of iron in the
